OUPS!!
While laying in bed last night I got to thinking about the camber etc. and realized that the camber on a tadpole trike is to permit center point steering (the king pin is angled towards the center of the wheel) but using a fork to mount the wheel, center point / camber is out the window.
My next quandary is reinforcing the cross boom since the 1.5 inch box tubing is being compromised due to the headset being welded in the middle. Thinking of just welding an 1/8 inch x 1.5 flat bar across the front to eliminate ANY chance of flexing.
